WHY YOU SHOULD PAY ATTENTION TO BOILER WARNING SIGNS
Your combi boiler is at the heart of your home. From showers to central heating, it plays a crucial role in your everyday comfort. However, even the most reliable systems can show wear and tear over time.
Whether you're dealing with low boiler pressure, no hot water or heating, or strange noises from your boiler, addressing problems early helps you avoid long-term damage.
At Maintracts, our team is highly experienced in identifying and resolving London combi boiler problems before they escalate. We're here to keep your system running efficiently and safely.
COMMON SIGNS YOUR COMBI BOILER NEEDS REPAIR
1. No Hot Water Or Heating
If your combi boiler isn’t delivering hot water or your radiators are staying cold, something’s wrong. This is one of the most common combi boiler issues we respond to.
It could be caused by:
- A faulty diverter valve
- Broken thermostat
- Issues with internal sensors or the pump
Don’t settle for cold showers—book a professional combi boiler repair in London to get your heating system running smoothly again.
2. Strange Noises From The Boiler
Whistling, banging, or gurgling sounds are often signs of trapped air, blockages, or the buildup of iron oxide within your system.
Common causes include:
- Air in the pipes
- A failing pump
- Blocked filters
These noises may start off subtle but will worsen over time if left unresolved. For professional diagnosis, book with Maintracts today.
3. Low Boiler Pressure
A typical pressure reading should be between 1.0 and 1.5 bars. If your boiler regularly drops below this level, it may not function properly—or at all.
Possible reasons:
- Leaks in the system
- Faulty pressure-reducing valve
- Bleeding radiators recently
Persistent low pressure is a clear indicator that you need a combi boiler repair in London. Left unattended, it could lead to more significant problems and higher repair costs.
4. Error Codes On Boiler Display
Modern combi boilers are fitted with digital displays that indicate faults through error codes. While these codes vary by manufacturer, they often relate to:
- Ignition failure
- Temperature sensor issues
- Circulation faults
If your boiler displays an error code, don’t try to guess its meaning. Contact a certified boiler technician in London who can accurately diagnose and repair the issue.
5. Water Leaking From Boiler
A leaking combi boiler in London is not just inconvenient—it’s a serious concern. Water leaks can damage internal components and pose a safety risk.
Causes include:
- Corroded pipes or joints
- Broken seals
- Pressure issues
Leaks typically begin small and gradually worsen over time. We recommend turning off the system and contacting a qualified engineer immediately.
6. Radiators Not Warming Up
Radiators that remain cold or heat unevenly may suggest:
- Air trapped in the system
- Build-up of debris in your radiators or boiler
- A broken circulation pump
These problems reduce heating efficiency and increase energy bills. Our gas boiler repairs in London include comprehensive system checks to restore your radiators to full performance.
7. Boiler Keeps Turning Off
If your boiler repeatedly shuts off without warning, it could be due to:
- Overheating
- Blocked filters
- Pressure loss
- Sensor or thermostat malfunctions
You may need a system reset or a deeper repair. We offer same-day boiler repair in London for urgent problems like these.
8. Smell Or Discoloured Flame
If you detect a strange smell or the pilot light burns yellow (instead of blue), shut off your boiler immediately. This could pose a risk of carbon monoxide exposure, a serious health hazard.
Don’t attempt to fix this yourself—call us on 02086822244 for a fast response.
